Get it so it works. Then adjust accordingly.
Set up a process, however bad. Your first port of call is simply whether it works or not. Even if it splutters and breaks, as long as the process works, all that’s left is to fine tune it again and again. Before long, the wheels will be running smoothly, and you’re well on your way to glory.
The hardest part is getting it started. Everything else from there is mere adjustment.
